(v2) Line Number Gutterfunc Adjustments

[meowgorithm]

Ideally, we'll want to be able to style the bar differently than the line numbers in this guy:

// LineNumberGutter return a [GutterFunc] that shows line numbers.
func LineNumberGutter(style lipgloss.Style) GutterFunc {
	return func(info GutterContext) string {
		if info.Soft {
			return style.Render("     │ ")
		}
		if info.Index >= info.TotalLines {
			return style.Render("   ~ │ ")
		}
		return style.Render(fmt.Sprintf("%4d │ ", info.Index+1))
	}
}

On that note we should also add a func that is just line numbers with no bar.

i mean, yes, the default one should probably be simpler, and leave specifics to the caller

I this one is so nice though, could keep it in as a bonus with two args.

yeah, looking at it now, i think it would break if lineno > 9999 though

Ah, indeed. In general, it might be good to get either the max lines, or maybe better yet, the model as an arg for more context and set widths accordingly.
